[Abstract]:With the deepening of petroleum exploration and development, the status of heavy oil reservoir production becomes more and more important. At present, it is difficult to obtain good results by conventional thermal recovery technology for ultra-heavy oil reservoirs and asphaltene reservoirs with huge reserves. In steam assisted gravity oil recovery, submersible oil pump plays an important role. As the power part of submersible pump unit, submersible motor is the key to ensure the normal operation of the whole unit. Its performance directly affects the quality and life of the whole electric pump unit. The submersible motor works thousands of meters under the well, and there are many factors affecting its reliability. In this paper, the submersible motor which can work in high temperature environment is designed and the temperature field in different environment is calculated. Surface content is analyzed and studied: first of all, The application background and function of submersible motor are introduced. The basic structure and characteristics of submersible motor are introduced. The research status of the key technologies of submersible motor and high temperature motor at home and abroad is described in detail. The main dimensions and electromagnetic load parameters of the motor are designed, and the influence of high temperature environment on the electromagnetic material performance of the motor is studied. The two-dimensional model of the motor is established, and the rationality of the design of the motor parameters is verified by the electromagnetic calculation results of the finite element software. Secondly, through the finite element and analytical calculation, the loss of the submersible motor is obtained, which is mainly mechanical loss. After determining the boundary and initial conditions, the three-dimensional thermal model of submersible motor is established, and the fluid field is set up. The temperature distribution and temperature rise of the submersible motor under normal condition are simulated by 3D finite element software, and the high temperature resistance performance of the designed submersible motor is verified. Finally, the temperature rise distribution of the submersible motor under different working conditions is analyzed. At the same time, the temperature rise experiment and field test of the designed submersible motor are carried out, and the results are compared with the simulation experiment. The correctness of the motor design and simulation experiment is verified.
